From the photographer: "This telephoto scene shows the planet Jupiter above some communications antennas and a sightseeing tower in Froson, Sweden. Jupiter's bright moons are from left to right, Callisto, Europa and Ganymede." - Goran Strand

Editor's note: Visible in this image are 3 of the 4 Galilean moons orbiting the gas giant planet Jupiter. These 4 large moons were discovered by Galileo Galilei more than 400 years ago.
